To all takovit may concern) V Be it known that I, JOSEPH J. DONEGAN,

and useful?Improvement in Lawn-Sprinklers, ofwhich the tollowi'ngisa complete:

specification."

The :p esent invention pertains to sprinkling devices, and aimsto devise a novel formeof lawn or garden sprinkler having an improvedarrangement and construction of parts andproviding aCsimplified and more etlicient "device of this character. 2

" One of the objects of the invention is to provide a lawnor garden, sprinkler having a water'wheel actuated from a jet nozzle,

-said wheel for producing a travel of said wheel bodily about a vertical axis. this purpose have devised [an improved bearing structure for' ournahng -the parts 0f the device "for a said movement or travel about a'vertlcal .;ax1 s,-the' said arms com cidingwith the axis of the water connection.

A further ieature "of the improvement comprises an improved@coupling device adapted to form the connection between the a water hose; or conduit and gthe sprinkler de vice and havin rovision also. for the attachment of supporting legs" for-the suitable supportbf the device in operati'vej position.' 2* It is furthersought to devise animprov'ed arrangement of thegear connection between I JFigure lis avi thewater wheel and the bearing structure whereby thewate'r wheel and the jet nozzle member are actu'ated'about a vertical axis. Further features of the improvement'will appear in the course of the detailed de scription, which will new-#136 made with reference to the accompanymg drawing illustrating one form of construction which I have devised for embodying the invention after which the novel features therein will be set forth in the appended claims.

eferring now to thesaid drawing in detail, this illustratesthe improvedsprinkler device as adapted to be connected to a hose or other water conduit membenterminat "111g 1n" a nlpple or pipe section 7 adapted to be received in a couplingf'rnemb'er' 8,

L which member is formed with a plurality of inclined recesses or sockets 9. These. sockets 9 are designed, for the reception: of the [upper ends ofa plurality of legs 10 fors'upporting the sprinkler L operative position, the said upper endsof device in upright and the legs lO being clamped in the sockets-9 means of clamping screws 12, while, the r iloWer ends'of the legsare tapered "or point-] ed, as shown in Fig. l, for adapting the same to be'iirmly embedded in the soil, in J an obvious manner.

It Threaded into" a recess 14 in the upper end of end of a tubular bearing member 15, havthe coupling-member 8 is the lower 7 orstatlonary gear wheel 16 (see Fig. 2).

said sleeve havinga flange 18 fitting within the base of the recess'l and abutting M tween the upper end of the bearing 15 and thegear -wheel 16 and,aroundthesleeve 17.

Also secured to the upper end of the sleeve 17 is a supporting structure which comprisesa housing member 24secured to-said sleeve by means one. clampingscrewj25,

as shown in the said housing member havin formed, nearthe margln thereof, an uprig t tubular bearing post 26 for the journaling of an upright shaft 27, the lower end of which p v shaft is provided with a pinion 28 meshing place-by means of screws 32. At one sideof the worm .wheel is journaled a hori-" zontal' shaft. 33?.having bearings: said housing 29 and carrying aworm 3e meshing with the teeth of the worm gear 30. one

struction-forcarrying out the proposed obtained constant. As said: wheel' rotates un- 'derthe'action' of the jet from the nozzle the above describedv ear connections between the wheeland the xed bearing 15 will .obviously impart a'bodilytravel ofthe wheel and its described supporting structure about the axis'of said fixed bearing 15, the 0b "jectxof which, of course, is tq distribute thesprav from the sprinkler device over a considerable area of which the said device is the, center; deem the present construction V andwarringernent of the supporting "structure for the nozzle and wheel andthe gear connection therebetween to be a material iniprovelnent overthe types of construction heretofore employed forproducing a travel of the water wheel in a path about a vertical axis, a more effective 7 action being obtained 7 by ahnlng the hose connection wlth the-noze zle pipQQO and carryingthesamedirectly 1 throughEthe. axis of; the vertical bearing.
